"Verily, thus saith the Lord unto you my servant Stephen Burnett: Go ye, go ye into the world and preach the gospel to every creature that cometh under the sound of your voice.
Wherefore, go ye and preach my gospel, whether to the north or to the south, to the east or to the west, it mattereth not, for ye cannot go amiss."
What this made me ponder on is how even without the calling of missionary, every member of the church of Christ is to testify of him. It is an obligation to stand as a witness at all times, in all things, and all places. I think this is why the Lord is telling Stephen Burnett it doesn't matter where you go, you cannot go amiss if you are testifying of Him.
